the point of the turbo is to create boost, obviosuly the more boost the harder the turbo is working, correct you are, but it is still creating power. Not to sure how familar you are with dsm's or anything, but recently the 14n turbo has finally broke into the 10's. 20lbs of boost isnt that much for a 16g as long as you have the fuel and tuning needed. get on the srtforums.com and read aaronsneon how to 300whp on the stock turbo, its a good thread.

supporting mods are the key as everyone knows
